    Volume of water the BMC supplies to the city and its suburbs every day. BMC has been supplying the same quantity of water even during the COVID-19 lockdown indicating increased usage for domestic and residential purposes in light of increased personal hygiene practices as well as added stay-at-home demands - from running tap water to wash germs off fruits and vegetables to continuous rinsing of hands with soap followed by several rounds of bathing, laundry, cooking and cleaning - had perhaps led to increased water usage and subsequent depletion.
